Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed January 12. 1906- Serial No. 295,674.

To all whom it may concern:

Be it known that FRANK IIUMIHREVILLE, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, has in vented certain new and useful improvements in Shoe- Polishing Machines; and he does hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of thisinvention is to provide a satis factory shoe polishing machine adapted to operate conveniently on the shoes of several people successively or simultaneously in different seats or standing places. To this end, I- employ a sliding gear driven by any convenient power, a flexible shaft rotated by said gear and sliding with it and a brush carried by said shaft, as well ascertain cooperative parts and special details of construclioi'r, all as more particularly hereinafter set forth and claimed.

In the accompanying drawings, Figure i represents a front elevation of a shoe polishing machine embody ing my invention, iucasod Fig. 23 represents a rear view of the same, the outer casing and protruding parts being removed; Fig. 3 represents a detail plan view of the shifting gear and its frame; Fig. 4 represents a do tail side elevation of section Y and rod W hereinafter described, the former being shown in elevation, the 1atter in cross section. Fig. 5 represents an end elevation of the entire machine incased; and Fig. 6 reprcsents a horizontal section through Fig. 3, certain parts being shown in elevation.

A designates a long seat for the persons whose shoes are to be polished; B, a series of foot-rests below the same; (I, a back it said seat; D, electric lamps behind the foot-rests and attached to sockets (1111 a space 1) under said scat, E, end pieces of said seat at right angles to said oat G, a longitudinal slot in the front of the machine casing below said seat and foot rests; and if, a lower platform.

1, .l' and K designate drawers for loose articles such as the motor starter, extra brushes, blacking die, arranged as convenient in different parts of the front of said casing.

A driving shaft L is mountcd behind slot G on a frame M, preferably secured to the flooring or any fixed )ZISO normally within the casing of the seat and under the latter. An electric motor P, secured on the same base, drives the said shaft through belt 0 and pulleys 0 0 thereby rotating also any convenient mnnbor of flexible biuslrcarrying shafts geared to said driving shaft and extending outward through said slot. We have illustrated in the accompanying drawings only one of said flexible shafts, marked R, but its duplication or multiplication at will is readily understood. The gearing between these two shafts consists of a bevel friction wheel P as hereinafter stated, feathered on the driving shaft for adjustmdnt along the latter anda corresponding friction pinion Q, turning with the said flexible shaft. and mounted in a bracket T, having two inwardly extending arms which end in hubs L surrounding the elongated feathered hub or sleeve P of wheel I. One half of each hub L is integral with the said bracket, thc'otherhall being bolted thereto through oorrcsponding flanges t of said hubs. Said sleeve has an annular shoulder 1" which forms a backing for said wheel and may be considered as practically a part of it, though the wheel proper is non-metallic and preferably of vogetablefiber, affording a good friction surface and easily replaced when worn. (ollars t are fast on said sleeve in proximity to both ends of the left hub t, and aid the shoulder I. aforesaid and a peripheral enlargement of the right end of said ,sleeve in holding the hubs l in position and preventing their enduise slip thereon. The. said sleeve is readily slipped along the driving shaft to any point where it may be needed, the said gear wheel, bracket, pinion and flexible shalt moving with it, and the slot (1 allowing said flexible shaft to run straight out from the main shaft at any point to which it may thus be adjusted, so that the minimum length of flexible shaiting may be employed. The said bracket T is provided with a cylindrical recess T" in its inner face, receiving a corrcspomling integral cylindrical stem Q of said friction pinion Q and allowing the latter at will to be drawn back out of contact with the wheel. Said brackethas also a cylindrical rearward int cgral tubular bearing '1 centrally bored for the passage of a short. inflexible shaft X, on which the pinion Q is fastened, so that the said pinion and this shaft move together both axially and longitudinally, as though integral.

'lhc outer end of shaft X is slotted or bifurcated at X to rcceivc thc rcduccd inucr end I of the coupling stern R of flcxiblc shaft lt, these parts r and X permitting ill(l01i) 'll(ltl1l. longitudinal adjustment of shaft and pinion Q without moving outwardly or inwardly the flexible shaft It, although thcse shafts it and X turn togcthcr. Shaft X is also provided with a collar or annularshouldcr X integral with it or fixed thcrcon. This ln-ld bctwecn two opposite shoulders y and 2 of tubular scctions Y Z which, with the said bracket, complete the bcariug casing of shaft X. Each of these sections has a rearward cylindrical rcccss concentric with said shaft, that of the inner section Y receiving the said bearing 'l" of the bracket '1; and the similar recess of scction Z receiving a corrcspon din g extension Y of section Y. At this point a set screw Z fast cuss the said sections Y and Z so that they must move together, both rotativcly and longitudinally. In said section Y is formed an oblique slot Y receiving a scrcw or stud Y (Fig. 3) of the fixed bearing T A bundle U fixed to section Z facilitates the turning of said sections together and such axial movement by the contact of the inclined driving shaft L and fitting into a transverse groove V walls of the said slot with the said fixed stud moves the said sections Y Z outward or inward longitudinally according to the direction of motion of the handle. The

. shaft X of course participates in this endwise shifting of the said sections by reason of the arrangement of the collar X between shoulders y and z and in contact therewith. 4

An additional extension or tip Z is fastened by a screw Z on an outward extension Z of section Z and has an enlargement Z of its central bore to receive the rear end of the flexible shaft B, said bore receiving and fitting the said coupling stem of said flexible shaft. This tip Z of the shaft casing turns with the sections Y Z in the above described axial movement for endwise adjustment and also moves endwise with them during the same, but permits the shafts R and X to turn Withdut impediment in said shaft casing. The section Z and tip Z protrude through the slot G in the front of the mhchhie and the brush S may rest on platform 1-1 when but of use or be applied from any direction, lightly or firmly, to any part of the shoe which is'undergoing polishing and rotated to effect that result. Practically the parts Y, Z and Z constitute collectively an independ- V ,ently adjustable extension of bracket-T, which is the bearing of the flexible shaft and its friction pinion Q,

their function being to provide for gearing or ungearing the latter at Will. Of course if this function were dispensed with the bearing and easing might be simplified and my invention is not confined to the inore convenient construction shown. v

The handle U is of course available to move the flexible shaft and'intervening devices longitudinally of the shaft as well asfor the connectionand disconnection of such gearing.

W designates a fixed guide rod or bar parallel with the in the underside of section Y.- This rod supports the outer part of the said section and the corresponding part source of power may of course be substituted for the ceases electric motor above referred to; but it is the most convenient where electric connections may easily be made.

The especial construction of the foot-rests shown is not claimed in this application, being claimed as well as mole particularly set forth in my application No.

' 295,312 filed concurrently herewith.

It is not'necessary that the short shaft X should b independent of the flexible shaft R in axial movement.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a shoe brushing machine, the combination of a driving shaft with a flexible shaft,.a brush carried-by the latter, gearing between said shafts adapted to be shifted along said driving shaft, and a seat-supporting casing slotted opposite said driving shaft to permit the direct outward extension of said flexible shaft from any point of the driving shaft to which it may be shifted.

2. In a shoe-brushing machine, the combination ofa driving shaft with a flexible shaft, 9. brush carried by the latter, a bracket providing a bearing for a short shaft attached to the flexible shaft, a wheel having its hub feathered on the main shaft and movable along the latter with said bracket, a pinion on said short shaft and driven by said wheel, the said short shaft, means for connecting it to said flexible shaft and a seat supporting cas-' ing which inclosessald main shaft and is providedwith a horizontal slot in its front to permit the protrusion of said short shaft and the shifting of said wheel and bracket along said main shaft substantially as set forth.

3. In a shoe brushing machine, the combination of areas ing, :1 motor and driving shaft iuclosed thereinfgearing' driving shaft with a flexible shaft, a brush carried by theunder side to receive the same substantially-as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
